W&T Com-Server LC server seriale per dispositivi, RS-232/422/485 a Ethernet, guida DIN 58661

Legacy serial devices often remain stranded outside modern IP networks, creating costly integration gaps. The W&T Com-Server LC bridges RS-232, RS-422, or RS-485 equipment directly onto 10/100 Mbps Ethernet, enabling seamless remote access and control without replacing existing hardware. This compact, DIN-rail mountable unit delivers reliable serial-to-Ethernet connectivity for industrial automation, building management, and legacy system upgrades.

Who is it for

System integrators, industrial engineers, and IT administrators who need to network-enable serial devices such as PLCs, meters, sensors, barcode scanners, or CNC machines. Ideal for factory floors, utility cabinets, and distributed installations where space is limited and reliability is critical.

Main features

• One software-selectable serial port supporting RS-232, RS-422, and RS-485 (2/4-wire) via D-Sub 9-pin male connector
• 10/100BaseT Ethernet port with auto-negotiation for easy LAN integration
• Wide range of network protocols: TCP/IP, UDP, DHCP, DNS, SNMP, HTTP, FTP, NTP, SMTP, and Telnet
• Serial tunneling with RFC2217 and Modbus/TCP client/server for industrial applications
• Galvanic isolation on the serial port protects against ground loops and surges
• Flexible power input: 12–48V DC via terminal block, typical consumption only 1.5 W
• DIN rail mountable plastic housing (IP20) for quick installation in control cabinets
• Configuration via web browser, Telnet, Windows tool, or SNMP; firmware upgradeable

Specifications

• Serial baud rates: 300 bps to 230.4 kbps; data bits 7/8, stop bits 1/2, parity none/even/odd
• Flow control: RTS/CTS and XON/XOFF
• Operating temperature: 0°C to +70°C
• LED indicators for status and diagnostics
• Management protocols: SNMP, Telnet, HTTP
• Supported network protocols: TCP/IP, UDP, DHCP, DNS, SNMP, HTTP, FTP, NTP, SMTP, Telnet

Tips

For best performance, assign a static IP or DHCP reservation to avoid address changes. Use the integrated web server for quick setup and firmware updates. When connecting RS-485 multi-drop networks, ensure proper termination and biasing for reliable communication over long distances.
